Yes, had mine live since January '18
Was in two minds but the decision was made for me when it was looking like I might have to work from home due to the weather conditions (the office was going to be closed if it snowed but people would work from home and me and colleagues were expected to keep an eye on things to make sure they could) and right on cue my broadband started to flap (3 km line which used to be affected when people started getting lots of Christmas lights out with badly shielded adapters)
Luckily for me it didn't snow on the Monday but rang and placed the order as it worked out about what I was paying for line rental and ADSL.
Wondered why I didn't do it sooner.
